Woodpeckers (Picidae)

White-barred Piculet (Picumnus cirratus) - HBW 7, p. 428

French: Picumne frangé German: Zebrazwergspecht Spanish: Carpinterito Variable
Other common names: Pilcomayo Piculet (SW races)

Taxonomy: Picumnus cirratus Temminck, 1825, Brazil and Paraguay.
Forms a superspecies with P. dorbignyanus and P. temminckii, and sometimes treated as conspecific with one or the other, or both; hybridizes frequently with latter in SE Brazil (São Paulo and Paraná), also occasionally with former in Bolivia. Also interbreeds to limited extent with P. albosquamatus and apparently with P. varzeae. SW races thamnophiloides, tucumanus and pilcomayensis intergrade in N Argentina, and sometimes considered together to form a separate species, but last of those also intergrades with nominate race in E Paraguay.

Also interbreeds to limited extent with P. albosquamatus and apparently with P. varzeae. SW races thamnophiloides, tucumanus and pilcomayensis intergrade in N Argentina, and sometimes considered together to form a separate species, but last of those also intergrades with nominate race in E Paraguay. Also, N races confusus and macconnelli possibly form a distinct species. Further study needed to clarify relationships of this entire complex of taxa. Six subspecies currently recognized.

Subspecies and Distribution:

  • confusus Kinnear, 1927 - SW Guyana, extreme N Brazil (E Roraima) and French Guiana.
  • macconnelli Sharpe, 1901 - E Amazon region of NE Brazil (W to lower R Tapajós).
  • thamnophiloides Bond & Meyer de Schauensee, 1942 - SE Bolivia (Chuquisaca) S along Andes to NW Argentina (N Salta).
